After adding too much coolant, it may cause excessive pressure in the coolant expansion tank. The introduction of automotive coolant and precautions when filling are as follows: Introduction: The full name is antifreeze coolant, meaning it is a coolant with antifreeze function. Coolant consists of three parts: water, antifreeze, and additives. According to the different components of antifreeze, it can be divided into alcohol type, glycerol type, ethylene glycol type, and other types of coolant. Precautions: Do not open the cap rashly when the radiator "boils." Do not spill water on the engine when adding water. Avoid human contact with antifreeze. Do not mix different types of antifreeze. Do not operate the engine without water. After the water inlet shows full, start the engine and let it run. When the engine temperature rises to the point where the thermostat opens, the air in the water jacket will be expelled, and the water level will drop. At this time, refill the radiator to full.

What is the function of a sunroof?

The function of a sunroof is to clear fog, quickly remove odors, provide an escape route, and reduce exhaust fumes entering the car. Installed on the roof of the vehicle, a sunroof effectively promotes air circulation inside the car, allowing fresh air to enter while also expanding the field of vision and meeting the needs of mobile photography and videography. Sunroofs can be broadly categorized into: sliding-out, built-in, built-in flip-up, panoramic, and curtain types, primarily installed on commercial SUVs, sedans, and other vehicle models. Sunroofs change the traditional method of air exchange by creating a flow of wind that draws out stale air from the cabin. When driving at high speeds, air flows rapidly around the vehicle. Opening the sunroof creates a low-pressure area outside the car, and due to the difference in air pressure inside and outside the vehicle, it draws out the polluted air inside, achieving the purpose of air exchange. This ensures the cabin always maintains fresh air, enhancing the driving experience for the owner.

What does tire size mean?

Tire size indicates the dimensions of a tire. Generally, the tire size used by a vehicle is printed on the sidewall of the tire. Different types of vehicles use different tire sizes. Taking a tire model of 250/60R15 as an example, 250 represents the width of the tire; 60 represents the aspect ratio of the tire; R stands for radial tire; and 15 represents the size of the tire. Car tires are one of the important components of a vehicle, directly contacting the road surface and working together with the vehicle suspension to mitigate the impact during driving, ensuring good ride comfort and smooth driving. They also ensure good adhesion between the wheels and the road surface, improving the vehicle's traction, braking, and off-road capability.
